Abstract: A delivery system for continuous release of fragrances, repellents, attractants, and the like is disclosed. The substance to be released is comprised in a sheetlike polymer matrix. By virtue of the fact that this polymer matrix is in wound form, the substance to be released can be released from the delivery system continuously and over a relatively long time period.

Abstract: A sheetlike article comprising a single-layer homogenous matrix containing at least one active substance such as a crop protection agent, biocide, fertilizer, plant strengthener, cosmetic substance or fragrance, is produced by applying the at least one active substance to at least one of two layers of identical composition, placing the two layers atop one another so as to enclose the at least one active substance, irreversibly joining the layers with the at least one active substance therebetween under pressure to form a laminate and storing the laminate under defined conditions for a duration sufficient to effect migration of the at least one active substance into the base layer and connection of the layers at their interfaces.
